Summary

A phase I dose escalation study of veltuzumab and milatuzumab in relapsed and refractory B-cell NHL. The phase I study will be followed by a pilot phase II study.

Detailed description

A phase I/II study of veltuzumab combined with milatuzumab in relapsed and refractory non-Hodgkin's lymphoma. Both agents are well-tolerated in early phase clinical testing with infusion reactions as the primary observed toxicity. Preclinical testing in vitro and in vivo have demonstrated single agent activity for both veltuzumab and milatuzumab. In mantle cell lymphoma cell lines and SCID mouse models, synergist effects were observed when milatuzumab was combined with rituximab. Veltuzumab has several advantages over rituximab including slower off-rates, shorter infusion times, higher potency, and improved therapeutic responses in animal models. Previous and ongoing clinical investigations support the concept of combining monoclonal antibodies in NHL.

Interventions

Type	Name	Description
BIOLOGICAL	milatuzumab	Patient will receive milatuzumab weekly for 4 total doses during induction therapy. Induction therapy will be defined as the first 4 weeks of study therapy. During week 1 of induction therapy, patients will receive milatuzumab on day 2. Starting in week 2, milatuzumab will be given on day 4. Provided the patient does not experience excessive toxicity or disease progression during induction therapy, the patient may continue treatment with extended induction therapy, consisting of veltuzumab day 1 and milatuzumab day 4 of weeks 12, 20, 28, and 36.
BIOLOGICAL	veltuzumab	Patient will receive veltuzumab weekly for 4 total doses during induction therapy. Induction therapy will be defined as the first 4 weeks of study therapy. Provided the patient does not experience excessive toxicity or disease progression during induction therapy, the patient may continue treatment with extended induction therapy, consisting of veltuzumab day 1 and milatuzumab day 4 of weeks 12, 20, 28, and 36.
PROCEDURE	Correlative/Special Studies	To correlate Fcγ receptor polymorphisms with response to treatment with the combination of veltuzumab and milatuzumab. Whole blood will be collected pre-treatment on day 1.
PROCEDURE	Quantitative T-, B-, and NK cell subsets	Quantitative T-, B-, and NK- cell subsets will be assessed using flow cytometry to quantify the percentage and absolute number of cells expressing CD4, CD8, CD56, CD16, CD19, and CD20 pre-treatment on day 1, after induction (week 5, day 1), and prior to the start of therapy on day 1 week 12, day 1 week 36, and then every 4 months for one year.
PROCEDURE	Pharmacokinetics	To assess the pharmacokinetics of veltuzumab in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma. Pharmacokinetics will be assessed with blood samples collected at the following time points: immediately pre- and post-infusion on day 1 of weeks 1, 2, 4, 12 and 36. One additional sample will be collected each of weeks 5 through 10 (sample may be collected any day during each of these weeks).
PROCEDURE	Pharmacokinetics	To assess the pharmacokinetics of milatuzumab in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma. Pharmacokinetics will be assessed with blood samples collected at the following time points: immediately pre- and post-infusion on day 2 of week 1 and day 1 of weeks 2, 4, 12 and 36. Additional samples will be collected days 3 through 6 of week 1.
PROCEDURE	Human Anti-Human Antibodies	To monitor for the development of human anti-veltuzumab antibodies and human anti-milatuzumab antibodies (HAHA) in patients receiving treatment with veltuzumab and milatuzumab. Patients will be monitored for the development of HAHA at the following timepoints: pre-treatment on day 1 of week 1, pre-treatment on day 1 of week 4, pre-treatment on day 1 of week 12, and pre-treatment on day 1 of week 36.
BIOLOGICAL	veltuzumab and milatuzumab	Patient will receive veltuzumab and milatuzumab weekly for 4 total doses during induction therapy. Induction therapy will be defined as the first 4 weeks of study therapy. During week 1 of induction therapy, patients will receive veltuzumab on day 1 and milatuzumab on day 2. Starting in week 2, veltuxumab will be given on day 1 and milatuzumab will be given on day 4. Provided the patient does not experience excessive toxicity or disease progression during induction therapy, the patient may continue treatment with extended induction therapy, consisting of veltuzumab day 1 and milatuzumab day 4 of weeks 12, 20, 28, and 36.
